1 Claim.

The present invention relates to a fastener for detachably connectingthe ends of articles such as necklaces, bracelets, and beads.

The object of the invention i to provide a fastener for articles of thetype mentioned which may be economically manufactured due to its simpleconstruction, and which is of an attractive appearance suited for use inconjunction with ornaments.

It is a further object of the invention to provide a fastener which isreadily and simply connected and disconnected, and which, whenconnected, provides a sure fastening for the article even under extremeconditions of activity on the part of the wearer.

With these and other objects in view, the invention generally comprisesatop and a bottom lamina, the bottom lamina having a staple fixed along aportion of its longitudinal axis, one end of the article to bedetachably connected being attached to said staple, the other end ofsaid article being attached to the top lamina. The top lamina isprovided with an orifice having a width sufiiciently great to permit thepassage of said bottom lamina therethrough when the longitudinal axes ofthe two laminae are substantially at right angles but not under anyother conditions, said orifice being shaped 50 as to snugly receive saidstaple, and to hold the two laminae in face-to-face fixed abutment whentension is applied to the two ends of the article to be detachablyconnected, after passage of said bottom lamina through the orifice insaid top lamina and reception of said staple in said orifice.

Other objects of the invention will be made apparent from a study of thefollowing specification in conjunction with the accompanying drawings. I

In the drawings- Figure 1 is a plan view looking down upon the fastenerof my invention in a connected position.

Figure 2 is a side view of the fastener, again in a connected position.

Figure 3 is a cross-sectional view of the fastener taken along the line3-3 of Figure 2.

Figure 4 is a perspective view of a modification of the fasteneraccording to my invention, showing the bottom lamina inserted throughthe top lamina but not in the connected position, and

Figure 5 is a perspective view of the modification of Figure 4 showingthe bottom lamina being inserted through the top lamina,

In the drawings, like reference characters indicate like partsthroughout the figures. In the accompanying drawings I0 is a bottomlamina having a staple i l disposed along the longitudinal axis thereof.One end ii of the article to be detachably connected is attached to thestaple H. A top lamina i3 has the other end is of the article to bedetachably connected attached to a staple i5 fixed to the upper surfaceof top lamina l3 and disposed along a portion of the longitudinal axisthereof. The top lamina 53 has an orifice iii having a widthsufficiently great to permit the passage of the bottom lamina Iiitherethrough, when the longitudinal axes of the two laminae aresubstantially at right angles but not under any other conditions.Orifice it is also cut away so as to snugly receive the staple ii whenthe two laminae are aligned in face-toface abutment with their twolongitudinal axes in the same plane.

It will be seen that if bottom lamina H1 is inserted through orifice L3in top lamina l3, and the two laminae aligned in face-to-face abutmentwith staple H snugly received by the cut away portions of said orificeitpthen if tension is applied to two ends l2 and i i of the article tobe detachably connected, a secure fastening will be formed.

I prefer to make top lamina is wider than bottom lamina ac and toprovide top lamina is with two side bars ll and 98, one side bar beingdisposed along each longitudinal edge of the undersurface of top laminal3. Side bars ii and it are adapted to prevent angular movement ofbottom lamina iii relative to top lamina it, when the two laminae aredisposed in face-to-face abutment with staple ll snugly received in thecut away portions of orifice I6.

Figures 4 and 5 show a modification of the fastener according to myinvention, in which the end E2 of the article to be detachably connectedis made in the form of a relatively large link. With this modification,I do not employside bars but depend upon the action of this link i2 inconjunction with the snug reception of staple H in the cut away portionsof orifice iii, to restrain bottom lamina ill from angular movement withrespect to top lamina l3, when the two laminae are in the connectingposition previously described. When in this position, tension applied toends l2 and H! of the article cause large link iii to bear fiushlyagainst the upper surface of top lamina i3, giving a jamming effect.

. From the above specification and from the accompanying drawings, itwill be seen that I have disclosed a fastener which meets the objectspreviously set out as desirable.

It is intended that the present disclosure should not be limited in anyway other than that indicated by the scope of the following claim,

What I claim as my invention is:

A clasp of the class described comprising a first member and an orificedsecond member, matching principal surfaces on said first and sec andmembers, a staple extending from the matching principal surface of saidfirst member to a height substantially less than the Width of said firstmember, the longitudinal axis of said staple being substantiallyperpendicular to the width of said first member, the length of theorifice in said:

second member being of sufficient dimensions to accommodate the width ofsaid first member and to snugly receive said staple when said matchingsurfaces abut in clasping relationship, the maximum width of saidorifice beingv substantially less than the width of said first memberand the length of said staple and being of sufficient di- 4 mensions toaccommodate the elevation of the staple on the first member togetherwith a chain attachable thereto when said first member is passed throughsaid second member. 7
